Evidence of inception horizons in karst conduit networks

Laurent Tacher, Marco Filipponi, Pierre-Yves Jeannin

This paper outlines the conclusion from an analysis of 18 large cave systems around the world, comprising more than 1500 km of conduits. The 3D geometry of complex cave systems have been analysed in relation to their geological context as well as their hyd ...

Sharing is Harder than Agreeing

Rachid Guerraoui

One of the most celebrated results of the theory of distributed computing is the impossibility, in an asynchronous system of

n

processes that communicate through shared memory registers, to solve the set agreement problem where the processes need to deci ...

Integration of plasmonic optical traps in microfluidics - art. no. 69880V

Olivier Martin, Lina Huang

We study the integration of plasmonic traps with microfluidic channels. Plasmonic traps are optical traps that use the evanescent field generated by metallic nanostructures at their plasmon resonance to trap small objects. Contrary to conventional - far-fi ...

Apraxia: a review

Olaf Blanke, Aude Billard, Biljana Petreska von Ritter-Zahony

Praxic functions are frequently altered following brain lesion, giving rise to apraxia - a complex pattern of impairments that is difficult to assess or interpret. In this chapter, we review the current taxonomies of apraxia and related cognitive and neuro ...

Minkowski sums of polytopes

Christophe Weibel

Minkowski sums are a very simple geometrical operation, with applications in many different fields. In particular, Minkowski sums of polytopes have shown to be of interest to both industry and the academic world. This thesis presents a study of these sums, ...

On Trust Models and Trust Evaluation Metrics for Ad-Hoc Networks

Georgios Theodorakopoulos

Within the realm of network security, we interpret the concept of trust as a relation among entities that participate in various protocols. Trust relations are based on evidence created by the previous interactions of entities within a protocol. In this wo ...

Sobolev inequalities for differential forms and $L_{q,p}$-cohomology

Marc Troyanov

We study the relation between Sobolev inequalities for differential forms on a Riemannian manifold

(M,g)

and the

L_{q,p}

-cohomology of that manifold. The

L_{q,p}

-cohomology of

(M,g)

is defined to be the quotient of the space of closed differential ...

Variational Image Reconstruction from Arbitrarily Spaced Samples: A Fast Multiresolution Spline Solution

Michaël Unser, Michael Sühling, Muthuvel Arigovindan

We propose a novel method for image reconstruction from nonuniform samples with no constraints on their locations. We adopt a variational approach where the reconstruction is formulated as the minimizer of a cost that is a weighted sum of two terms: 1) the ...

Influence of the substrate's surface morphology and chemical nature on the nucleation and growth of microcrystalline silicon

Arvind Shah, Xavier Niquille, Julien Claude Bailat

Hydrogenated microcrystalline silicon (μc-Si:H) layers about 500 nm thick were deposited in the same run on flat and rough substrates (rms = 60 nm) of various chemical nature. This study reveals that the spatial distribution of the microcrystalline/amorpho ...
